INTRODUCTION
•RPO
•Microen-capsulation materials
Materials
•Homo-genization
RPO emulsion
•Drying
MRPO
Boundary conditions:• High viscosity of RPO• Suceptibility of
b-caroten to high T
Suitable dryer
-
OBJECTIVES
1
• to determine the most suitable drying equipment for producing
MRPO
2• to study the drying parameters of
the chosen drying equipment
-
METHODS
RPO was produced in pilot plant scale of oil line
production at SEAFAST Center.

Material formulation
Emulsification
Drying of the emulsion
Mikroencapsulated RPO
METHODS
-
METHODS
The drying experiments were conducted by using tray dryer, drum
dryer, and spray dryer
The drying time and drying process performance were evaluated,
and quality attributes of MRPO were measured.

-
RESULTS
The position of the tray and the thickness of the RPO emulsion
layer affected the drying time, moisture content, and drying
rate
The thickness of emulsion layer will determined drying time and
drying rate to achieve the same moisture content
The recomended emulsion layer thickness with good drying process
parameters for tray dryer was 1.5 mm
-
CONCLUSIONS
Tray dryer can be used for producing high quality of MRPO,
regarding of b-carotene contents and recovery during drying
process.
The process efficiency of tray dryer must be improved by using
continuous drying system
